diferences with openldap2.3

There is some diferences betwen the version 2.3 and 2.2, when we configured the clients files, cause i have noticed that now when i do ldapsearch -x, slapd dont showme information about users, machines...anything...and before i could see all database, and now Im doing id user...and it give me backan error saying that the user dont exists...and it's in teh database...
the conf is the same that i had when i had openldap 2.2.x installedsome idea
